IMPROVEMENT IN MACHINES FOR COVERING CORD.

Specification forming part of Letters Patent No. 137,360, dated April 1, 1873; application filed January 31, 1873.

To all whom it may concern:

Be it known that we, J osnrn E. GILLEsPIE, of Norwich, in the county of New London and State of Connecticut, and TOBIAS KOHN, of Hartford, in the county of Hartford and State of Connecticut, have in vented certain new and useful Improvements in Machines for Covering Cords; and we do hereby declare that the following is a full, clear, and exact description thereof, whereby a person skilled in the art can make and use the same, reference being had to the accompanying drawing and to the letters of reference marked thereon.

Our invention has for its object the more perfect covering of a cord with a more costly material, and also in a more rapid and less expensive manner than has heretofore been done.

' It also has for its object the rendering the cord when finished more soft and pliable than as commonly made. Our invention consists in a peculiar construction of guides whereby the several covering-threads are properly conducted to their positions upon the cord. It also consists in a central core, which is introduced between thecord and the covering-strands in such a manner that it is covered with the cord and allows the latter to slip 01f when finished. It also consists in certain combinations and ar-. rangements ofthe several parts of the machine;

In the accompanying drawing, Figure 1 is a plan of. a machine embodying our invention. Fig. 2 is a vertical section of the same taken through its center from 1 to 7.

A is the bed-piece of the machine. B is an upright post or stud fixed in the bed-piece A. It has a hole through its center for the passage of the cord to be covered, and also contains the core or wire to be wound in with it. C is the bobbin-plate, revolved upon the post B by means of the cone-pulley D. I I are upright spindles upon the plate C to carry the bobbins 1, 2, 3, 4, &c. C is a circular rib upon the top of the plate C, reaching up to about half the height of the bobbins and leaving a hollow space in the interior next to the post B The top of the post is rounded and does not extend above the rib C. E is the top rail of the frame of the machine. F is an arm attached to the rail E by the set-screw e, which passes through a slot in F. G is a conical or hemispherical guide. It isfitted into the lower part of the arm F, and is held in place by means of the set-screw f. This guide has a hole through it for thepassage of the cord K, and can be accurately adjusted to its position over the post B by means of the set-screws e and f. H is a central coreformed of wire or other suitable material. It is attached to the frame of the machine by means of a clamp, L, and passes up through the post B and the guide Gr, alongside of the cord K, and is inclosed with it by the covering-thread. This wire remains in place as the covered thread passes upward, and draws out from the finished cord, leaving it soft and flexible.

The operation of our invention is as follows: The cord K passes from a reel up through the post and guide with a continuous motion, and is wound, as finished, upon another reel above in the usual manner. Bobbins are placed up on the plate 0 and their threads attached to the central cord. When the machine is set in motion these threads are wound around the cord and cover its surface as it passes upward. The guide G serves to conduct them into their proper relative positions upon the cord when drawn from the upper ends of the bobbins, and the rib C prevents the threads from passing below its level when coming from the lower end of the bobbin. The core or wire H is in cased with the cord, the covering-threads being wound tightly around both. As it draws out it leaves the threads released and the finished cord soft and flexible.

The advantages of our invention are: That itprodu'ces a better-covered and softer cord than formerly; also, that the threads can be more easily reached and tied when broken than in the ordinarymethod where they pass through holes in a guiding-thimble. As more threads can be used in our improved machine than before, they lie at a less angle along the cord and not sfisquare across as formerly, thereby presenting a better appearance, more nearly conforming to that of a cord made wholly of the more expensive covering material. The work can also be done more rapidly, as. a greater number of threads can be used.

Claims. 3. The central core H, in combination with a cord-covering" mechanism substantially as WVhat we claim as our invention isand for the purpose herein described.

1. Thecircularraisedrib 0 upon the revo1v-- 4. The combination of the rib C and the in g bobbin-piateGover which the threads pass, guide G with a series of bobbins, substantialsubsta ntiaily as and for the purposeherein de- 1y as herein described. scribed. J. E. GILLESPIE.

2. The guide G'for conducting the covering e T. KOHN.' threads upon the cord, and through which the finished cord passes upward, when provided Witnesses: with adjusting-screws and combined with the THEO. G. ELLIS, frame, substantially as herein described. WM. F. DYER.
